Estimating output/potency from QWET process?

Any thoughts on how to estimate potency for QWET process? Is it as simple as weighing the final oil once dried? Or is there a good calculation/formula to work with? I've read a few things where people are getting 12 or 15% and I'm not sure how that's been measured and/or how to calculate. I'm generally using cannabis that 'lists' 20-23% or so, and I knock that down by a few percent due to breeder 'inflation.'

Just trying to figure how to dial into my desired zone for edibles when making some gummies. Having made chocolates a few times, I can say that most calculators online when you're doing estimates read too high per-serving than what I'm getting.

You have to step back and think here. Those percentages you are seeing are the THC% of the flower tested and will only show you what your yeild should ballpark. You are taking said flower, stripping the cannabinoids off and concentrating them. Your QWET should be much closer to the 80-85% range or so.

I understand that in terms of concentration, but when it comes to translating that into how it works for dosing, I should take the end weight of the oil figure it at 80-ish% for THC and work that for my recipe's per-serving strength?

850 mg a gram...That's what I have always done with my RSO/FECO. It really helps out if you can use a 10ml/20ml syringe and a good scale. Freeze oil on a silicone baking sheet for a few min and then you will be able to roll it up like a tootsie roll and load it into syringe. Don't try sucking it up in there.

I've been reintroducing a small amount of alcohol (98%) to liquefy then adding that to my recipes. But the important thought is that I can weigh the end oil and calculate from there, and that will help me have a good idea of the end strength of what I'm making. In my case, what I have right now is in the bottom of a few ball jars...so that's easy enough for me to weigh clean/unused jars, weigh the full ones and then subtract out the jar weight.

We typically yield 18 to 25% essential oil from the strains we use. My one time lowest was 5.7% for a land race strain (Harlequin), and highest using QWET was 21.6% (God bud).

This helps. I weighed a few of the batches I have (reduced in smaller 4 or 8oz canning jars) and they range...the smallest ended up being 5.5% and the largest being 15%, but I've used flower from a few different plants along the way (Durban Poison, Tangerine Dream, Northern Lights) which range from a published 18% to 23%.

I'm going to try a slightly extended wash, 10 minutes instead of 5 and see what that ends up doing. I've washed up to 2 or 3 days and had useable extraction for edibles that ended up not being super weedy tasting, which is really my end game with this. The more recent extractions I've done have been to do two 7g 1st washes with ~5oz of 98% alcohol.
